The effect of different normalizing and tempering temperatures on the microstructure and mechanical properties of plastic mold steel 3Cr2NiMo was studied. The results showed that after normalizing at 810 ℃ and 840 ℃, the martensite lath was short and fine needle shaped with uniform structure, and the original austenite grain size was Grade 11. After normalizing at 900 ℃, the microstructure became coarse, and the original austenite grain size was Grade 9. The normalizing hardness increased first and then decreased with the increase of temperature. It was determined that the appropriate normalizing temperature of the test steel was 840 ℃. When the tempering temperature ranged from 450 ℃ to 500 ℃, the microstructure was tempered troostite, and the lath structure maintained the original martensite orientation. When the tempering temperature was increased to 650 ℃, the microstructure was tempered sorbate without obvious orientation. Subsequently, the carbides became spherical, aggregate and grow, while remaining uniformly dispersed. Moreover, the lath boundaries appeared blurred. The hardness of the test steel decreased with the increase of tempering temperature.

研究了不同正火、回火温度对塑料模具用钢3Cr2NiMo组织及力学性能的影响。结果表明,试验钢经810 ℃和840 ℃正火,马氏体板条呈短小的细针状,组织均匀,原始奥氏体晶粒度均为11级;经900 ℃正火后,组织变得粗大,原始奥氏体晶粒度为9级。正火硬度随温度的升高呈先增后减的趋势,通过分析并确定试验钢适宜的正火温度为840 ℃。回火温度为450~500 ℃时,组织为回火屈氏体,板条组织保持原马氏体位向;回火温度升高至650 ℃时,组织为回火索氏体,无明显位向,碳化物呈球状,聚集长大,均匀弥散分布,板条合并边界模糊。试验钢随回火温度升高硬度不断下降。

研究了不同正火、回火温度对塑料模具用钢3Cr2NiMo组织及力学性能的影响。结果表明,试验钢经810 ℃和840 ℃正火,马氏体板条呈短小的细针状,组织均匀,原始奥氏体晶粒度均为11级;经900 ℃正火后,组织变得粗大,原始奥氏体晶粒度为9级。正火硬度随温度的升高呈先增后减的趋势,通过分析并确定试验钢适宜的正火温度为840 ℃。回火温度为450~500 ℃时,组织为回火屈氏体,板条组织保持原马氏体位向;回火温度升高至650 ℃时,组织为回火索氏体,无明显位向,碳化物呈球状,聚集长大,均匀弥散分布,板条合并边界模糊。试验钢随回火温度升高硬度不断下降。

The effect of different normalizing and tempering temperatures on the microstructure and mechanical properties of plastic mold steel 3Cr2NiMo was studied. The results showed that after normalizing at 810 ℃ and 840 ℃, the martensite lath was short and fine needle shaped with uniform structure, and the original austenite grain size was Grade 11. After normalizing at 900 ℃, the microstructure became coarse, and the original austenite grain size was Grade 9. The normalizing hardness increased first and then decreased with the increase of temperature. It was determined that the appropriate normalizing temperature of the test steel was 840 ℃. When the tempering temperature ranged from 450 ℃ to 500 ℃, the microstructure was tempered troostite, and the lath structure maintained the original martensite orientation. When the tempering temperature was increased to 650 ℃, the microstructure was tempered sorbate without obvious orientation. Subsequently, the carbides became spherical, aggregate and grow, while remaining uniformly dispersed. Moreover, the lath boundaries appeared blurred. The hardness of the test steel decreased with the increase of tempering temperature.
